Nickel ferrite (Ni x Fe 3x O 4) have been synthesized using solid state reaction with composition (2x)NiO : (3x)Fe 2 O 3 (x = ; ; dan ) in mol in wt%. Mixing of this powder was milled with HEM (High Energy Milling) for 10 hours, and then sintered at 1000 °C for 3 h. Xray diffraction pattern indicates that the all of samples are single phase in this stage.

•FeSiBCuNb amorphous microwires have been ballmilled for times between 6 and 30 min. Pyrex has been removed by a magnetic method, and pyrexfree microwires 10 μm length have been ball milled with ferrite. Wire morphology and the influence on the ferrite's energy products BH max was studied by SEM and hysteresis loops.
The structural and magnetic evolution in copper ferrite (CuFe2O4! caused by highenergy ball milling are investigated by xray diffraction, Mo¨ss spectroscopy, and magnetization measurements. Initially, the milling process reduces the average grain size of CuFe2O4 to about 6 nm and induces cation redistribution between A and B sites.

Abstract. Nanocrystalline magnesium ferrite is synthesized at room temperature by high energy ball milling the MgO and αFe 2 O 3 (1 : 1 mol fraction) powders. The Rietveld structure and microstructure refinements of Xray powder diffraction data of 9 h milled sample reveal the presence of mixed and nearly inverse spinel nanocrystalline Mgferrite phases.
Lithium ferrite (LiFe5O8) is a cubic ferrite, belongs to the group of soft ferrite materials with a square hysteresis loop, with high Curie temperature and magnetization. The spinel structure of LiFe5O8 has two crystalline forms: ordered, βLiFe5O8 (Fd3m space group) and disordered, αLiFe5O8 (P4132/P4332 space group). It has numerous technological applications in microwave devices, computer ...

A study by Bid et al . showed the formation of ZnFe 2O4 could occur within only 30 minutes of ball milling with homogeneous stoichiometric (1:1 mol%) powder mixture of ZnO and Fe 2O3 phases. The reduction of intensities of the starting materials in the course of
The polycrystalline nickel ferrite NiFe2O4 has been obtained by ceramic route starting from a stoichiometric mixture of oxides (NiO and αFe2O3 powders). The obtained NiFe2O4 was subjected to high energy ball milling. The formation of NiFe2O4 by ceramic method and also the evolution of the powder during milling were studied by Xray diffraction.
Ferrite is a bodycentered cubic (BCC, alpha iron) form of is this crystalline structure which gives steel and cast iron their magnetic properties, and is the classic example of a ferromagnetic material.  It has a strength of 280 N/mm 2 and a hardness of approximately 80 Brinell.  Below 910 °C (1,670 °F) the bodycentercubic allotrope of pure iron is stable.
